STRIP smi-veta.

Appueaaon med February 11, i924. seriai No. 692,153.` l

This invention relates to improvements in strip shingles, i`or covering the roofs or walls of buildings, vformed preferably of roofing felt, or material of similar nature, with a mineral covering or surface usually formed of iinelydivided. slate, stone, gravel, or similar material.

The present inventionis an improvement` on the strip shingle shown and described inl i0 Letters Patent ot' the United States issued tome August 14thl923, N0. 1,464,4A92.

The invention consists generally in the constructions and combinations' hereinafter described and particularly pointed out in the 15 claims.

In the accompanying drawings, Figure l is a plan view of a single shingle embodying my invention.

vFigure 2 is a plan of a sheet of material, or a portion of a sheet, illustrating the manner in Which-Vthe strip shingles may be cut therefrom.

Figure?) `is'a plan view showing a pre- 'erred manner of laying the shingles to iorml a 'roof or wall covering.

In the drawing, 1 represents the body portion of the strip shingle, lwhich may be formed, in the usual way, of a foundation sheet of wool felt,with a coating or layer of pitch, asphalt, or the like on one surface of the felt, and a' layer of crushed slate, stone, gravel, or similar material pressed into the coating and held in place thereby.

I form, at one `edge ot' the body, projecting extensions', or butts, 2, 2, here Ashown of rectangular form, separating. spaces '3, 3, being provided, each equal in outline or contour, and area to theoutline, contour and area of each of the butts 2, so that a rectangular sheet, such as shown in Figure 2, may be divided as indicated by the dotted lines, 5, 5, and 7,7, extending longitudinally of the sheet, and the transverse lines 6, 6, and 8, 8.

In starting manufacture of the shingle from a double strip as indicated in Figure 2, there Willbe at thev end of the strip two small corners, e, e, will be no further -Waste until the-opposite end of the sheet is reached.v In producing this stripl shingle the butts, 2, 2, are located atthe same distance from the ends of the body of the shingle, tliatisto say, the line a-f,\ that measures the distance .from the right hand butt to the end of the shingle strip is equal to the line a/-g that measures which will be wasted, but there thedistance from the left'hand butt to the left hand end of the shingle, and each of these lines is equal to one-half the'length of` the line cwhich measures the/distance between the inner edges of the butts and the vertical lengths of the butts 2-2 vwill be one-half the horizontal width of the separatwhich in turn are substanvertical width to the body l ing spaces 3 3 tially equal the ot' the shingle which enables me tocut the l shingles from" rolls as'above indicated with# out waste except at 'the corners of the ends of the. roll. This produces an entirely sym metrical shingle, and when the shingles are -laid on a root' in overlapping relation, as il-V lustrated in vFigure 3 of the drawings, the root will not only have a symmetrical ap' pearance but every part thereofwill have at, least two layers of material covering it.- Moreover as will be observed rom'aninspec- 4tion of Fig. 3, the shingles are arranged on the roof in the ordinary courses with the ends .of the body portions of the shinglesl abutting each other. The butts lie tlat on the body portion of. the shingles of the underneath lower course of shingles, the butts having the same contour of the spaces between the butts vmakes it possible to cut from a single strip of material two sets of shingles on a severing broken line 5-5, Fig. 2, without material waste of material. When theI shingles of an upper layer aredisposed as shown in Fig. 3, from those in' the lower layer, the distance oi' a butt, the joints vbetween the meeting edges of the shingles are broken and the butts extend in vertical relation one directly above the other, and there would always be a' double thickness of solid material to vbreak the joints between the butt,

endsot' the body portions of the shingles. Il do not limit myself to any particular size or dimensions of the parts, nor to any particular material for forming the same.

I claim-as my invention,

l. A strip shingle comprising a body por'- tion having a 'plurality of separated butts. projectingfrom one edge thereof withA sides 'perpendicular thereto throughout vto their ends, the size and contour ofeach butt corresponding to the size and contour of the/ separating spaces between two butts, the distance between the 'outer edge of each but-t andthe end of the 4shingle being equal to one-.half the distance between the inner edges of the butts and substantially equal to the length of the butt, and the length ofthe butts being :qiproxirnatelyl one-hall the width of the body ofv the shingle.

il. A roof comprising courses of shingles, each shingle comprising a body portion having a butt projecting from one edgethe'reof, each butt being separated a distance from either end oi' the shingle, each butt on the roof being-"spread out flat and extending down mter the body portion of the` shingle or .sl'iiugl's Aofa lower course offshingles, the sizeand-contour of each butt corresponding to the size and contour of the separating spacel between two companion butts when the. slungles are-hud in the ordinary courses i on the-roof, the ends of the body portions.

abutting each other, theend edges'of the body of the shingle being perpendicular t'o the points where the edges of the butts meet the lower edgeof the body of the-shingle to the l weredge of the butt inall the shingles oi a course being equal .to one-half-'the length of the loweredge of each butt and substantially equal to only halfthedista'nce from the top to the bottom ofjthe body of Vthe .shingle whereby twov sets of shingles may be cut on a' single continuous broken-line from a rectangular sti-ipI of shcetmaterial,

the. body portion ol" the shingles'being. sev! ered from cach other on lines extending :1pproximately from thel middle point of a separating vspace between companion butts." i In witness whereof I have hereunto set my hand this 5th of February, 1924.
